Think on paper, together.
A live whiteboard for small teams: boxes, lines and arrows that link and follow each other, a laser pointer for showing, and a history you can step back through and branch from.
- Live. Everyone on a board sees every stroke as it happens. The server draws the whole picture; your browser only shows it.
- Branching history. Every change is kept. Jump back to any moment, and draw a new branch from there.
- Yours, or everyone's. Draw on the global board, a public board anyone with the link can join, or a private board for the people you invite.
